为探究不同杀菌条件对蓝点马鲛鱼(Scomberomorus niphonius)品质的影响,本文研究了110℃、46.4 min(A组),115℃、14.7 min(B组)和121℃、3.7 min(C组)3种杀菌条件对鱼肉感官品质、脂质组成及风味的影响。结果显示,杀菌后蓝点马鲛鱼的质地、滋味和气味的感官评分变化明显。样品中的总脂、甘油三酯和磷脂含量在杀菌后均显著降低(P<0.05),游离脂肪酸含量显著升高(P<0.05)。不同杀菌组间脂质组成存在差异,C组样品的脂质损失程度最高。脂质氧化程度受杀菌条件的影响显著(P<0.05),过氧化值(POV)含量均显著升高、硫代巴比妥酸反应值(TBARS)含量显著降低(P<0.05)。电子鼻分析结果表明,不同杀菌条件处理后鱼肉的气味特征明显不同。借助气相色谱-离子迁移谱从4组样品中鉴别出22种挥发性化合物,各组间的挥发性物质存在明显差异,其中,己醛、戊醛、异戊醛、3-戊酮、环己酮、3-羟基丁-2-酮和乙酸乙酯等是鱼肉中的主要风味物质,在B组样品中含量最高。综上,采用115℃、14.7 min(B组)杀菌的样品,其感官和风味品质明显优于其他组,且脂质氧化程度更低。研究结果可为蓝点马鲛鱼罐头产品加工提供参考。

The reclamation is the main method in the coast exploitation, and the assessment of the hydrodynamic environment effect of the reclamation project is important for project's site selection and environmental protection. With consideration of the baroclinic water, a 3?D numerical model MIKE3 is applied to simulate Yangtze Estuary's hydrodynamic environment to predict the impacts of the reclamation project of the Nanhui tidal flat. The simulated results of the model agree well with the field data of the tide level, the current speed, the current direction, the temperature, the salinity and the water quality, and it is indicated that after the reclamation project, the high tide level will be lower, while the low tide level will be higher in the South Branch in general. During the spring tide in the dry season, the peak velocity during the ebb tide in the North Channel will be reduced by 13%, while it will be increased by 21% in the South Channel in average. The salinity will be increased in the North Channel, while reduced in the South Passage, besides, the reclamation project will aggravate the saltwater intrusion of the North Branch. The value of N/P will be increased by about 4% in the whole South Branch except for the North Channel, leading to a slight aggravation of the phosphorus restriction effect in the Yangtze Estuary.

Objective While associations between the angioarchitecture of arteriovenous malformations （AVMs） in the brain and pathological features have been described, here we investigated the relationship between the angioarchitecture, the pathological features of the vessel wall, and hemorrhagic events. Methods The study was conducted on 43 patients： 16 with ruptured AVM （rAVM）, 15 with non-ruptured AVM （nrAVM）, 6 with craniocerebral trauma （control） and 6 with epilepsy （control）. The diagnosis of AVM was confirmed by preoperative digital subtraction angiography. Tissues were stained with hematoxylin and eosin and Masson＇s trichrome （for collagen fibers） to evaluate the vessel wall structure and endothelial integrity. The content and distribution of collagen types I and III in the vessel wall were assessed by immunohistochemical staining. Results In the nrAVM group, the nidus had more draining veins than the rAVM group （P 〈0.05）. Severely damaged endothelial cells, significantly fewer smooth muscle cells in the media, and hyperplasic type-I and -III collagen fibers were found in the rAVM group. The content of collagen types I and III in rAVMs was higher than that in the nrAVM （P 〈0.05） and control groups （P 〈0.01）. Conclusion There is an association between angioarchitectural features such as the number of draining veins and the pathological structure of the AVM wall. These abnormalities may contribute to AVM rupture.
